“It’s a small deal, the $3 million number is roughly accurate,” the source said.

Qlika raised nearly $2 million in venture capital since its founding in 2012. Qlika did not respond to emails for comment.

Qlika’s six employees will now be absorbed into the Priceline Group family of growing online properties. The deal shows how executives are increasingly looking to monetize the mobile advertising space by figuring ways of holding the interest of mobile users looking into the screens of smart phones, tablets, and wearables.

Specifically, Qlika’s team will be used to support Priceline’s Agoda website, a discount booking travel property focused on the growing Asian market. Priceline purchased the Singapore-based site in 2007.
